New solid roof = thermal excellence

Synseal has launched the Celsius solid roof, which it described as ‘a new and innovative system’ that employs a structural framework of timber components with ‘environmentally friendly’ Envirotile external roof tiles and cappings to create a ‘truly warm’ solid roof construction, with no possibility of cold bridging.

“At Synseal we have been monitoring competitor solid roofing products for a while and the market is now ready for our Celsius solid roof,” said Steve Brown, Synseal’s products and customer service director. “Sitting neatly alongside our exclusive Celsius performance glass, our new solid roof solution can be summed up in just two words: thermal excellence.”

At the heart of the system are thermally efficient structural insulated panels (SIPs), enabling the Celsius solid roof to achieve a pitched roof ‘U’ value of 0.18 W/m2K for compliance in England and Wales. The ‘U’ value of 0.15 W/m2K for compliance in Scotland is achieved by fitting insulated plasterboard to line and finish the solid roof interior.

“Selecting the right supply partners to complement our Synseal Envirotile was key to the success of Celsius solid roof and with structural insulated panels (SIPs) from Kingspan TEK Building Systems, fixings from Rapierstar and optional roof windows from Velux we have sourced the very best products to construct a well engineered system of the highest quality,” commented Synseal’s head of R&D, Phil Parry.

Synseal Envirotile external roofing components are injection moulded to Synseal’s exact specifications from 100% recycled polypropylene. Precision manufactured and lightweight, each single Envirotile has a low profile chamfered front-leading edge with an ‘aesthetically pleasing’ riven finish. Each tile is 12mm in thickness, weighs just 610 grams and is said to be ‘extremely simple to fix yet performs exceptionally’, securely locking into adjacent tiles without any need for battening, to form a quick-fitting and fully integrated roof covering. A single mechanical fixing point at the head in addition to the innovative interlocking design ensures that Synseal Envirotiles fit securely and easily, ready to withstand wind and weather.

According to Synseal, Envirotiles are 80% lighter than standard concrete tiles, weighing 8.4kg per square metre in contrast with cement or natural slate roof tile products that typically weigh 50kg per square metre.

Available in a choice of three colours: black, brown or terracotta, the interlocking Envirotiles are said to be self-draining, self-ventilating and branded with the Synseal logo for ease of identification. The single or double Envirotiles are easy to handle and cut on site for a precision finish at concealed hip or valley roof edge intersections

In addition to single and double roof tiles, the Synseal Envirotile range includes an elevated and interlocking ventilated ridge cap, radius end/apex cover, hip, hip end cap, gable end cap, dry verge, tile starter trim and push-fit screw cap cover to ensure a high quality aesthetic finish for each Celsius solid roof.

Fully approved and registered by the Local Authority Building Control (LABC), the Celsius solid roof is available for existing glazed conservatory roof replacements or new build applications in lean-to, Georgian, Gable and Victorian building extension styles.
